China will soon have to switch to IPv6Internet Protocol version 6. Evolution of the IP protocol which associates a machine on a network with an address coded in the form of a series of numbers… quickly, otherwise you simply won’t have an IP address. Indeed, the country is far behind the United States and Europe, which started the shift a few years ago. If it does not equip itself quickly, China could be out of IP addresses in 3 years.
IPv6 for an almost unlimited number of IP addresses
Let us recall some basic notions: the IP address is the identity card of a computer, on the networkLAN is the acronym for the English term Local Area Network, which can be translated into French by Local Network. Its definition consists of a set of gold…, unique to each router or modemModem is the contraction of modulator-demodulator. It is a device whose purpose is to allow communication with users of… on the Internet. It is also this sequence of numbers that can betray you if you download illegally … The addresses of the ipv4 protocolInternet Protocol version 4. Traditional protocol for assigning a network address in the form of a series of four numbers separated by poi…, currently the most used, are composed of a series of characters, each “sequence” is 4 bytes, and are most of the time represented by whole numbers, from 0 to 255. They are 4 in number. As for car license plates, all combinations of numbers will soon be exhausted, because with this ipv4 protocol, we can only make 4.2 billion addresses worldwide. It will therefore be necessary to pass to the higher stage: the ipv6. In this case, the identifiers, therefore the digits of the IP address, will be coded on 16 bytes, which opens up a multitude of possibilities. For easier reading, they will then be written in hexadecimal characters, which gives a succession of letters and numbers, instead of numbers only.
Free, a precursor of IPv6 in France
But such an adaptation supposes that Internet providers and computer equipment adapt to IPv6. And in China, the delay is great. To the point that the Chinese organization in charge of the Internet may make it a priority. China has boasted of having the highest number of Internet users in the world. If technological advances are not made in time, it risks stopping there. In France, Free had deployed ipv6 for its subscribers in December 2007. Orange, for its part, had made an experiment which seems to be abandoned. But Europe itself feels concerned, the European Commissioner responsible for the information society and the media Viviane Reding having even called, last May, for the ipv6 protocol to be widely used by public authorities and companies by 2010. We expect an advance from other French ISPs …
